Renewed November 1, 1933 Claims.

This invention relates generally to means for locking revolving doors and similar structures, and particularly to a mechanism for looking a revolving door from a distance therefrom, to-

- gether with means for unlocking the door at a distance therefrom, constituted by a new and novel arrangement and. disposition of parts whereby the features of novelty and advantage set out below are attained. It is an object of this invention to provide a simple, direct acting mechanism of this type, which is composed of few simple moving parts, and which is also easy to install and is inexpensive to manufacture.

It is also an object of this invention to provide a mechanism of the type described which is especially adapted for installation in banks, and other such public places, whereby in an emergency, a teller or other ofiicer may prevent egress from the bank or the like by locking the revolving doors thereof, and at the same time giving a signal to police ofiicers, guards, or the like persons, so as to bring aid needed in the emergency, the mechanism of the invention being easily incorporated in any bank or other electrical alarm system.

Another object of this invention is to provide a simple mechanism of the type described which is operated by means of electrically actuated magnets or motors.

These and other objects of the invention, its nature, and its composition and arrangement, and combination of parts will be readily understood by any one acquainted with the art to 5 which the invention relates, upon consulting the following descriptions of the drawings, in which:-

Figure 1 is a top plan View of the device of the invention shown associated with a revolving door structure-indicated in dotted lines.

Fig. 2 is a. front elevational view of the operating mechanism.

Fig. 3 is a transverse vertical sectional view through that portion of the mechanism mount- 4 ed upon the revolving door.

Fig. 4 is a sectional elevational view of the operating mechanism.

Fig. 5 is a transverse vertical sectional view through that part of the mechanism which is -mounted upon the revolving door.

Fig. 6 is a perspective view of the upper slide of the operating mechanism.

Fig. 7 is a perspective view of the toothed lock and Fig. 8 is a view of a signal light operating switch which is mounted upon the operating mechanism so as to light or extinguish signal lights according to the position of the upper slide thereof and Fig. 9 is a diagrammatic view of the wiring system of the mechanism of the invention.

Referring in detail to the drawings, the numeral 5 generally designates the operating mechanism of the invention, which is mounted below the rotating door structure generally designated 6 in Fig. 1, which revolving door has a central shaft 7 on which is mounted a toothed wheel 8 secured for rotation freely thereon, which toothed wheel is segmentally cut outas indicated at 9 in equal radians, to form webs 10 between which are disposed coiled springs 11 for engaging either side of an upstanding lug 12 on a wheel 13 which is keyed as indicated at 14 to the shaft 7, so that there is a yielding connection between the toothed wheel 8 and the lug equipped wheel 13, so that as thetoothed wheel 8 is rotated or is prevented from rotating, any shock upon the revolving door and other parts of the mechanism will be cushioned by the springs 11.

A suitable support 15 may be provided so as to carry the operating mechanism 5 in proper position as shown in Fig. 3. It will be obvious, that in order to lock the revolving door against rotation, the structure described above being connected thereto, it is only necessary to provide means to engage the toothed wheel 8 so as to prevent rotation thereof. Such a means is provided in the form of the operating mechanism generally designated 5. As seen in the drawings, the operating mechanism 5 consists of a base 16 of elongated form upon the outer end portions of which are mounted solenoid magnets 1'7 and 18 respectively.

On an intermediate portion of the base 16 between the magnets 1'7, 18 there is provided a guide 19 with a transverse passage 20 therethrough. Upon the upper surfaces of the guide 19 and at an opposite transverse side thereof are channeled members 21 which confine therebetween for longitudinal movement a slide 22 which has ribs 23 projecting laterally into the channel defined by the guide 19 and the members 21 as better seen in Fig. 3. The slide 22 has enlarged portions 2a which accommodate vertically, set screws 25 for engaging the ends of magnetic cores 26 and 27 which have their inward ends introduced in bores 28 in the enlargements 24, the cores being slidable in the magnets 1'7, 18.

As illustrated in Fig. 6, the slide 22 has a horizontal portion provided with a diagonal slot 29. Slidable in the transverse passage 20 in the guide 19 is disposed the latch generally designated 30, which has at one side the teeth 31 for engaging with the teeth 32 of the toothed wheel 8. A pin 33 rises from the upper surface of the latch and is slidably confined within said diagonal slot 29. The pin 33 is preferably arranged near the middle of the latch and at one side of the latchs longitudinal dead center.

When one of the electro-magnets 17, 18 is energized, the slide 22 will be drawn in the direction of the energized electro-magnet. Such a movement of the slide 22 causes the sides of its diagonal slot 29 to work against the sides of the pin 33 on the toothed latch 30. Since the latch 30 can move only in a path transverse of the path of movement of the slide 22, the toothed end 31 of the latch will be moved in a direction toward engagement with the teeth 32 on the wheel 8 or in a direction away from said wheel 8 depending upon which one of the electro-rnagnets 1'7, 18 is energized. Thus by energizing the proper one of the electro-magnets 1'7, 18 one may engage the latch with the wheel and lock the same against rotation or withdraw the latch from the wheel so as to permit the wheel to rotate freely. The operation of the device may be arranged so that the latch will be in its initial position when engaged with the wheel or when disengaged therefrom as may be convenient.

A suitable switch mechanism generally designated 34 may be mounted upon one of the stationary guide members 21 so as to be aii'ected by the movement of the slide 22, so that in one position of the slide the door will be free to rotate and a signal light will be maintained to indicate such position, and when the slide 22 is in the opposite position thereof, so as to lock the revolving door against rotation, a light will indicate the presence of an emergency, said light being preferably located at a police station or other alarm center, so as to provide for notifying of the existence of the emergency.

A method of wiring such an arrangement is indicated in Fig. 9. The solenoid 1'7 is connected to the power line or alarm circuit 35 which may lead to a police station and to a source of electrical energy, and a companion conductor 36 is broken by a switch 37 which may preferably be located in a police station or other selected location, so that the lock may be withdrawn and the door permitted to rotate only when the device is operated by the switch 3'7 at the place desi nated. 5

The solenoid 18 has one side thereof connected to a switch 38 located in the bank tellers window or other place in the bank or the like public place, and to the power line 36, and the remaining side of the solenoid 18 is connected to the conductor 35. The base of the switch 34 is connected as indicated at 39 with the conductor 38, and the movable member of the switch is connected through a lamp 40 to the conductor 35.

The lamp 40 is provided to indicate both in the bank and the police station or the like, that the door is open. Another contact of the switch at is connected thru a warning lamp 11 to the conductor 35 to give warning at the police station or in the bank or the like, that the door is closed and that an emergency exists. In one contemplated arrangement, the door can only be opened by the agency of the switch 37 in the police station, the switch 38 located within the bank or the like being effective only to lock the door, so that intruders cannot open the door.

It is believed that the above sufficiently describes the invention and the preferred embodiment thereof to enable any one acquainted with the art to which this invention relates to understand, make, and use the same, and accordingly further description is believed unnecessary.

It is to be definitely understood that I do not desire to limit the application of this invention to the particular modification set out herein, to illustrate the principles thereof, and any change or changes may be made in material and structure and arrangement of parts. consistent with the spirit and scope of the invention.
